As for zoom filters … I am wondering what they are all about … so many!
These are different smoothing algorithms.
If you need the best quality we suggest: Hermite, Bell, BSpline, Lanczos3, Mitchell, Nearest, Bilinear, Bicubic.
If you need speed we suggest: Triangle, Linear, FastLinear.
FastLinear filter is optimal in terms of quality and speed.
You can choose “best quality” filter, but it will work slower.
